Juan Carlos Silva -

Welcome!

Your fruitbowl scene is lovely. It looks like a painting. I always post feedback and suggestions, even to the images I like. In terms of shaders: the cherries probably need a little of that translucency effect that the grapes have, none of the fruit really seems to reflect other fruits near it, the center parts of the bananas are very brightly lit so much that they should be losing saturation or toned down, and the orange could use a whiter highlight since it is so bright. In terms of lighting, most of it is good, even with the mixed key direction. The tips of the bananas donā€™t really read as well as they could, Iā€™d think more light on the apple behind the upper one would bring it out. You can see some polygon facets here and there that could be subdivided or smoothed.

The kitchen images are great. Most of the surfaces are well shaded. (The wine bottle is the odd man out, it looks like plastic.) The floor is interesting with a nice texture. When most of the light is inside the scene, you might add some window glass to the window because I think people can notice it not being there. The only big lighting note Iā€™d add is that the sense of contact between the chair and the floor isnā€™t well enough defined (with shadows and occlusion) in the upper one, it looks as if the chair could be floating above the floor.

The chocolate scene looks like it was fun. You clearly are both talented and hard working, so I hope at some point in the future you come back and light something with hair or fur on it, thatā€™s a really common demand in high-end professional work.

I look forwards to seeing more of your work. Maybe youā€™ll do a Spaghetti Monster next, so youā€™ll be working on something in the same month as a lot of other people?

Hi Jeremy,

Thank you very much for your feedback. All the coments were very useful for me to improve my work. I am working very hard to build a good portfolio and see if I can land myself a job as a lighting artist in the US. I will go back and fix the problems you mentioned. Also, Iā€™ll get started on the spaghetti monster scene. That really looks like fun.

Thanks again.
Juan Carlos

Hi.
Seems that I jump from one challenge to anotherā€¦ probably Iā€™ll end having started all of them, but having finished none of themā€¦ lolā€¦ well I hopeā€¦ NOT.

So, this is my 1st eye-for-an-eye testā€¦ a lot to doā€¦ c&c=yippiehā€¦ thx.

Mesut.

Nice job! That eye looks good. In a real human eye, when you see it from the side, I think the color of the iris comes almost all the way to the front of the lens. This is due to refraction, but still thatā€™s how it looks to me.

Jeremy:
warriorash - Shadows are getting better, the ones on the right could still be softer. Also make sure the shadows appear in reflections, such as the vase. Maybe a little glow around the candle flames?

Hey Jeremy thanks for the comments again, you are very patient enough to reply to each and every one of us, well here the candle flame is glowing and i added a bit of reflection blur on the table and the vase, But do shadows appear on the reflections also, esp when the shadows are very diffused and blurry?

Hi there Jeremy,

Thanks again for looking at my scene. 1. What I did with this scene, was to get rid of the hot yellow spot on the ground, which was actually what you recommended me to do, which worked out just fine.

  1. It looks now like I have a better distribution of photons in the scene, I am not longer getting some random yellow spots around the scene, the scene now looks more of what I was going for, a semi bright foreground and a dark background, right by where the stairs are located, which makes sense since the spot light would not really fill up the whole room with light. So, the GI seems to do a pretty good job calculating that accordantly However, If you still think that it is to dark and that I need to bring the brightness up please let me know.

  2. I can definitely show the light source no problem, which is the bulb light right above it, The reason I did not show it was because the Ā“Light bulb meshĀ” was getting super bright and I couldnĀ’t figure out how to bring its intensity down, or how not let it be affected by the light source, but if you have any suggestions in how to go about it please do so.

  3. Your last question was, why am I using GI? why not? Lol, I guess is just a personal choice, I guess I like the way GI works and I am actually learning more about GI while working on this particular challenge, so, I am using it for learning purposes, and also as a personal preference. I tried using a spot light before, and a bunch of point lights in the scene and I was happy with the results, but I decided to start playing around with GI instead.

I will show the light source next time, once I fix the problem with the intensity, so that you can  review the overall scene, and I guess I will post both of so the scene, so that it is easier for you and others to see the changes I made, once again thank you so much for your inputs.

here are the two images that I have been working with.

Iā€™m new to this whole thing i hope this picture is not that bad, please comments and advices are very welcome.

Thanks.

#129

hi, thanks for the last comment jeremy. This is my latest wip, I added more volumetric to give more definition on where the ligh is coming from.

I think it can be more scary if I can put a girl on the stair just like the one in ā€˜The Ringā€™ movieā€¦hehehehe. Anyone interested to help me model one? :slight_smile:

By the way thanks again for the sugestion and I look forward for your comment jeremy.

neonbulbs - Nice job! If you get a nice girl model, please donate it to a future challenge. We need more challenges with characters in them.

hontonihanash - Welcome! See if you can get softer shadows and a softer edge to the main light in the ceiling. Thereā€™s some other bright spots (like around the wine bottle) that donā€™t seem motivated. The setting is interesting, I guess weā€™re in a moble home thatā€™s being transported down a freeway at night? You could work on the materials, too, right now the paper towels look more like chrome than the sink does.

warriorash - Nice job!

hi jeremy! Thanks a lot for the comment I really appreciated it. If I have any female character I will donate it to the lighting challenge because this challenge is so cool.

Thanks and happy lighting to all!

Cheersā€¦

Here is the hunted Hallway scene. As you can see the ā€œspot light meshā€ is super bright. I canā€™t figure out the way to fix this issue. The kind of light that I am using as a the source light it is an area light, that is located right below the ā€œspot light meshā€ which causes this this weird result. If you have any ideas in how to fix it that would be great, thanks again Jeremy.

#133

Thanks jeremybirn for your comment, hereā€™s my modified entry.
For the scene setup i didnā€™t intend it to be a mobile kitchen (even though it might look like this), i intended it to be a kitchen that looks out to a street.
I now worked more on the materials, got rid of bad reflections, and smoothed the shadows.
The bright spot under the bottle i think due to emitting caustics photon, the lamb on the ceiling is intended to be a lamb with a cover.
How do you think of it now?

Any comments are welcome thanks for advance.

#134

Thanks Jeremy, I updated the fruit bowl changing the intensity of the lights, and I made the second test for the kitchen.

#135

This is my final image, i have corrected some materials, (the fan, the chair, ā€¦), and corrected the lamb cover to be more transparent, err i forgot if i have done something else.

Please comment, thanks for advance.

#136

sgbzona - Work on the reflections of the fruit and the bowl - right now it appears as if the edge of the bowl has a bright reflection, but the rest of it doesnā€™t, and the fruit doesnā€™t reflect. For the room, it has very hard-edged shadows, they need to be much softer.

hontonihanash - Itā€™s a shame you still have the spotlight effect around the bottle, if itā€™s due to caustics you could just turn that off. It seems as if you might see some reflections in the window if you put glass there. The sink also could use some reflectivity so it looks like chrome.

Hi, I now have a bit more free time to work on my fruit bowl, so hereā€™s my latest effort:

I have updated a number of the materials and I am now using full global illumination. The actual lights are much the same as what I used before except I have removed the bounce lights as they seemed redundant now. Incidentally, I think my display setting are a bit off, so I would be interested to hear if the colours or gamma look odd to anyone.

Thanks for your help,

Chris

Chrisdc - Nice scene overall. The hard shadow cutting off the back of the banana is distracting. Most of the materials are almost there, the pear looks noisy and the apple a bit scratched up. Maybe tone down the orange stem and fill in the apple stem and leaf a bit?

Hello, Iā€™m a new comer to CGTalk. After I came across Jeremy Birnā€™s ā€œDigital Lighting and Renderingā€ book and website, I wanted to try my hand at lighting one of the challenges. Here are two renders from the bottles lighting challenge.

Hello everyone! Novice lighter here, recent graduate from Purdue. Iā€™m working on a few of the lighting challenges for my portfolio, please critique the hell out of these so I can get them looking as nice as possible. Iā€™m using a multi-pass rendering technique in Maya for the 3D work and Photoshop in post.

Thank you all for the help!
